INSIDE DOOR. FOR RAILWAY CARS AND THE LIKE.

Application filed July 8, 1922. Serial No. 573,542.

To all whom it may concern:

Be it known that I, ROBERT PEEL BnALr. WILSON, a citizen of the United States, residing at Hutchinson, in the county of Reno, State of Kansas, have invented a new and useful Inside Door for Railway Cars and the like, of which the following is a specification.

My invention relates to an improved inside door for box cars used in carrying grain and other commodities, and the object of my invention is,

First, to provide a practical door which may be used in said box cars over and over again when the box cars or other cars are loaded with grain and such freight.

Second, to provide a door which when not in use may be securely fastened to the inside of the box or other car and be practically out of the way.

Third, the provision of a small opening secured by a door, in the inside door which may be made any size or shape to suit, or may be left out altogether.

Fourth, to furnish a door of the character set forth which saves the expense and trouble of boarding up the doors of a box car when loaded with grain and such freight.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is an elevation of the inside door as it appears from the outside of the box car.

Figure 2 is a sectional view of the threaded tube or ferrule with flange at one end, the crank bolt being screwed into same, and through the inside door.

Figure 3 shows the inside door securely fastened as it appears from the inside of the box car.

Figure 4 is the front view of the crank bolt when fastened in place.

Figure 5 is the front view from the outside of the box car, showing the flange of the threaded tube or ferrule.

Figure 6 is a view of the top edge of the inside door, which may be bent at a right angle along the top,.or an angle iron attached to add strength.

Figure 7 shows that the top of or the edge may be looped along same to add strength.

Figure 8 is the interior view of the inside door, when securely fastened to the side of the box car when out of use, the crank is already found in the ordinary box car.

The fasteners of the inside door 3 are composed of a plurality of threaded hollow tubes or ferrules 4 each being provided with a flange at one end, in which ferrules are screwed the crank bolts 5. The threaded tubes or ferrules 4 are inserted in the door posts 1, 1, of the box car in a series, which is shown in Figure 1 and as shown by sectional view more plainly in Figure 2, said ferrules being angular in cross-section so as to prevent turning. The box car 1s equipped with a sutficient number of the threaded tubes or ferrules 4 which have a flange 6 and a number or series sufficient according to the size of the box car and inside door needed. In these figures are a series of four, threaded flanged hollow tubes or ferrules 4 which can be increased or decreased as necessary, that is a series on each side of vbox car door 1, 1, and one series to right of box car door with a corresponding number of holes 18 in the inside door 3. The inside door 3 is swung into place by means of two chains 15 which are attached to a rod or pipe 13 which may be the track from which the wheeled outer door is suspended being fastened to or near the roof of the box car, by means of brackets 14. The chains 15 slide along the rod or hollow pipe 13, to which they may be placed, and serve to keep the inside door 3, attached by links falling down or being lost or misplaced from the box car. When the inside door 3 is placed across the box car door as shown by Figures 1 and 3, then it can be securely fastened to the side posts 1, 1, of the box car by means of the crank bolts 5 and threaded tubes or ferrules 4. The crank bolts 5 are threaded at one end, while the other end is provided with a handle at rightangles with the bolt, and when screwed into the'threaded tubes or ferrules 4, after passingthrough the corresponding holes 18 will not unscrew themselves as the handles which are of sufi 17, 17, fromcient weight prevent them unscrewing, gravity holding them in place as shown in Figure The threaded tubes or ferrules a are equipped with a so that they cannot be pulled through the posts 1, 1, in which they are inserted and are countersunk, so that they are flush with the outside of the box car posts 1, l, as shown in Figure 1, they being held in place so that they will not shake out by means of two ordinary screws, 6, which latter also prevent turning of tubes or ferrules i, see Figures 2 and 5. The cranl; bolts 5 screwed through inside door 3 holes 18, have a flange 7, which turns against the inside door 3 and holds the inside door'3 securely against the ends of the threaded tubes or ferrules 4- which are placed in the box car door just flush with the inside of the box car door posts 1, l. The crank bolt 5 is attached to the chain 16 which is a chain lighter than chain 15 so that they will not be lost or misplaced being always handy for use, and are attached to chain 16 by means of yoke links 19 between the flanges 7, 7. The yoke links 19 allow the crank bolts 5 to be turned and screwed into place without twisting the chain 16 which holds them as shown in Figures 3 and 8. The inside door B or 3 may be reinforced or strengthened by means of angle irons according to the size of the door. The top of the inside door 3 may be strengthened by turning the top at a right angle to the door as shown in Fi ure 6 or by using angle irons, or the upper edge of the door can be looped as shown in Figure 7.

In the inside door 3 can be cut an opening 01 any shape or size, and as shown in Figures 1, 3, 8, which show a door 9, cut in the shape of a rectangle, with a hinge or bolt 11, which may be an ordinary bolt or rivet which holds it in place and allows the door 8 to be lifted or opened. The opposite end of the opening is a hook or clip 12, into which the extended or projected part of the door 8 drops or fastens, which holds same in place securely the door 8 being further secured by means of four or more stud bolts 10 which are screwed into the inside door 3. These stud bolts have to be unscrewed to allow the door 8 to be lifted or opened, and may be secured if desired by chains to the inside door that they will not be lost. By means or" the hinge 11, fastenings 12 and the stud bolts 10, the door 8 will not become loosened or opened so as to let grain or other freight run out unless and until they are removed if it is desired to open same to unload the grain or other freight.

Figure 8 shows the inside door 3 swung back to the right in the box car where to remain out of the way when not in use, and on the left shows the inside door 3 secured to the door post 1 of the box car. 611 the right of the inside door 3 the crank side (too; 3, she bolts 5, attached side door 3 is shown to 1 15 by links 1?, s are bored holes bolts 5, may pass throu into the thr aded tube secures inside door 3 i.
